The influence of the molecular weight is that the stability of the oil solidified product is 1 × 10 5 or more of S-B-S,
Effective in reducing the degree of adhesion. It has been clarified that the effect due to the difference in the styrene / butadiene ratio is related to the stability of the oil solidified product by the styrene portion and the difference in the oil absorption amount of butadiene if the molecular weights are the same. Similar results have been obtained. Furthermore, S-E-B to S-B-S
It was revealed that the stability of the oil solidified product was increased by adding -S. However, it is greatly affected by the difference in the properties of light oil. Based on the above results, S
